lacp-xmit-stdby
Syntax [no] lacp-xmit-stdby
Context config>lag
Description
This command enables LACP message transmission on standby links.
The no form of this command disables LACP message transmission. This command should be
disabled for compatibility when using active/standby groups. This forces a timeout of the standby
links by the peer. Use the no form if the peer does not implement the correct behavior regarding the
lacp sync bit.
Default
lacp-xmit-stdby

Syntax port port-id [port-id ...up to 16 total] [priority priority] [subgroup sub-group-id]
no port port-id [port-id ...up to 16 total]
Context config>lag lag-id
Description This command adds ports to a Link Aggregation Group (LAG).
The port configuration of the first port added to the LAG is used as a basis to compare to
subsequently added ports. If a discrepancy is found with a newly added port, that port will be not
added to the LAG.
Up to 16 (space separated) ports can be added or removed from the LAG link assuming the maximum
of 16 ports is not exceeded.
All ports, when added to a LAG, must share the same characteristics (speed, duplex, etc.). An error
message will be displayed when adding ports that do not share the same characteristics. Hold-timers
down must be 0. Ports that are part of a LAG must be configured with autonegotiate limited or
disabled.
The no form of this command removes ports from the LAG.
Default
No ports are defined as members of a LAG.
Parameters
port-id — The port ID configured or displayed in the slot/mda/port format.
priority priority — Port priority used by LACP. The port priority is also used to determine the
subgroup sub-group-id — This parameter identifies a LAG subgroup. When using subgroups in a

primary port. The port with the lowest priority is the primary port. In the event of a tie, the
smallest port ID becomes the primary port.
Values
1 — 65535
LAG, they should only be configured on one side of the LAG, not both. Only having one side
perform the active/standby selection will guarantee a consistent selection and fast convergence.
The active/standby selection will be signalled through LACP to the other side. The hold time
should be configured when using subgroups to prevent the LAG going down when switching
